Questions and answers

Buying a cargo on Tonargo follows four straightforward steps:

1. Calculate: Choose your product, quantity, and destination port in the price calculator. The engine routes the voyage and calculates the delivered price.
2. Send request: Sign in with a one-time code sent to your email. Your request is queued directly to our trading desk.
3. Desk Confirmation: Our desk reviews logistics and berth constraints, issuing a confirmed proforma invoice with fixed CIF terms.
4. Settlement & Voyage: Pay on-chain in your account. You can track vessel transit, status milestones, and messages with the desk in real time.

We sell export crude grades (Urals, ESPO Blend, Siberian Light, Sokol, Sakhalin Blend) and refined clean products (Ultra-Low Sulphur Diesel, Gasoline, Jet Fuel, Naphtha).

Cargoes load at major specialized export terminals across the Baltic Sea (Primorsk, Ust-Luga), Black Sea (Novorossiysk), and Pacific outlets (Kozmino, De-Kastri). Live terminal stock and chemical specifications (API gravity, sulphur, flash point) are updated in the Catalog.

Lot sizes correspond to standard tanker cargo capacities:

• Crude Oil: 55,000 to 140,000 metric tonnes (Panamax, Aframax, and Suezmax parcels — approximately 398,000 to 1,011,000 barrels).
• Refined Products: 30,000 to 90,000 metric tonnes (MR to LR2 tankers).

The calculator automatically converts barrels to metric tonnes based on the specific density of your selected grade and selects the optimal tanker class.

Since 2022 much of Russia's oil has sailed on a so-called shadow fleet: mostly older Aframax and Suezmax tankers insured outside the Western clubs, often moving cargoes ship to ship at sea. The sizes and the terminals are the same, so the calculator prices them alike.

The calculator provides an instant algorithmic estimate based on public market benchmarks. When reviewing a request, our trading desk assesses real-time vessel positioning, seasonal weather, and destination port congestion.

The desk may apply a commercial adjustment (discount or surcharge of up to 25% of the quoted total), accompanied by a clear transparent note detailing the reason. The initial quote is always preserved in your account history for comparison.

Prices re-evaluate server-side at the moment you click "Send request". If market benchmark prices or bunker costs have moved since you opened the page, no unconfirmed request is submitted. The interface displays the updated figures, allowing you to review before deciding.

Once your request is confirmed by the desk, you pay directly in your account. The exact payable amount in your chosen cryptocurrency (Bitcoin or supported stablecoin networks) is locked for a 20-minute window.

Transfers are detected automatically on-chain via dedicated blockchain verification nodes. Once the required network confirmations are registered, payment status updates instantly and loading instructions are dispatched.

You can add optional services directly beneath the price calculator:

• Independent Cargo Inspection: Quality and quantity verification by certified surveyors (SGS / Saybolt) at loading.
• Tank Cleaning & Readiness: Specialized pre-loading tank preparation for clean petroleum products.
• Guaranteed Laycan Window: Priority terminal berthing slot guarantee.
• Strait Risk & Escort: War-risk insurance cover and maritime security escort for passages through the Strait of Hormuz or the Bab-el-Mandeb / Red Sea corridor.

Yes. Tonargo provides standalone security and convoy coordination for any commercial tanker passing through high-risk corridors.

Submit a Passage Request with your vessel's IMO, flag, dimensions, cargo and expected arrival window. Our desk secures war-risk underwriters, coordinates convoy scheduling with naval escorts, and provides an official printable Transit Clearance.
